Success rates vary with the number of embryos transferred. However, transferring more and more embryos at one time does not increase the chance of live birth significantly, but may only increase the risk of a multiple pregnancy, and its associated risks. The impact of the number of embryos that are transferred also varies with the age of the woman.  

For women, intake of antioxidants (such as N-acetyl-cysteine, melatonin, vitamin A, vitamin C, vitamin E, folic acid, myo-inositol, zinc or selenium) has not been associated with a significantly increased live birth rate or clinical pregnancy rate in IVF according to Cochrane reviews.[30] The review found that oral antioxidants given to men in couples with male factor or unexplained subfertility may improve live birth rates, but more evidence is needed.[30]


Preimplantation genetic testing. Embryos are allowed to develop in the incubator until they reach a stage where a small sample can be removed and tested for specific genetic diseases or the correct number of chromosomes, typically after five to six days of development. Embryos that don't contain affected genes or chromosomes can be transferred to your uterus. While preimplantation genetic testing can reduce the likelihood that a parent will pass on a genetic problem, it can't eliminate the risk. Prenatal testing may still be recommended.

"Celiac disease and reproductive disorders: meta-analysis of epidemiologic associations and potential pathogenic mechanisms". Hum. Reprod. Update. 20 (4): 582–93. doi:10.1093/humupd/dmu007. PMID 24619876. Physicians should investigate women with unexplained infertility, recurrent miscarriage or IUGR for undiagnosed CD. (...) CD can present with several non-gastrointestinal symptoms and it may escape timely recognition. Thus, given the heterogeneity of clinical presentation, many atypical cases of CD go undiagnosed, leading to a risk of long-term complications. Among atypical symptoms of CD, disorders of fertility, such as delayed menarche, early menopause, amenorrhea or infertility, and pregnancy complications, such as recurrent abortions, intrauterine growth restriction (IUGR), small for gestational age (SGA) babies, low birthweight (LBW) babies or preterm deliveries, must be factored. (...) However, the risk is significantly reduced by a gluten-free diet. These patients should therefore be made aware of the potential negative effects of active CD also in terms of reproductive performances, and of the importance of a strict diet to ameliorate their health condition and reproductive health.
Stay positive. Search for success stories — there are so many out there. Look within your personal network or support groups to find other women who have similar experiences with infertility. Connect with them and share your stories. Learn what they have done, what doctors they have worked with, and what contributed to their successful pregnancies.
Artificial insemination, including intracervical insemination and intrauterine insemination of semen. It requires that a woman ovulates, but is a relatively simple procedure, and can be used in the home for self-insemination without medical practitioner assistance.[171] The beneficiaries of artificial insemination are women who desire to give birth to their own child who may be single, women who are in a lesbian relationship or women who are in a heterosexual relationship but with a male partner who is infertile or who has a physical impairment which prevents full intercourse from taking place.
IUI Preparation – Before your IUI procedure, men and women can make changes to their diet, add beneficial supplements or medications, and utilize holistic therapies like acupuncture and massage to ensure the best possible outcome from IUI. Taking this time to focus on improving the quality of your eggs pays off exponentially because it’s something you have the power to change. Best results are seen if adopted for 90 days prior to treatment.
The severity or complexity of infertility for you and your partner as a whole is also critical. Generally, patients are characterized as “subfertile” if there is only one infertility factor such as mild endometriosis, which can be improved through surgeries like laparoscopy. However, if both partners contribute infertility factors or one partner has multiple infertility factors, the chance of IVF success is significantly decreased. 

It’s not because you just ate a whole lot of greasy food (myth!). Sudden, out-of-control acne could be blamed on fluctuating hormones (from your period or menopause), a whole lot of stress, or a medication side effect. It may also be a sign of polycystic ovarian syndrome. That’s because in women with PCOS, ovaries make more androgen—the “male hormone”—than normal. Elevated levels may lead to adult acne flare-ups, as well as excessive facial or body hair, and even male-patterned baldness. These natural acne remedies may help your skin.

The main cause of male infertility is low semen quality. In men who have the necessary reproductive organs to procreate, infertility can be caused by low sperm count due to endocrine problems, drugs, radiation, or infection. There may be testicular malformations, hormone imbalance, or blockage of the man's duct system. Although many of these can be treated through surgery or hormonal substitutions, some may be indefinite.[57] Infertility associated with viable, but immotile sperm may be caused by primary ciliary dyskinesia. The sperm must provide the zygote with DNA, centrioles, and activation factor for the embryo to develop. A defect in any of these sperm structures may result in infertility that will not be detected by semen analysis.[58] Antisperm antibodies cause immune infertility.[23][24] Cystic fibrosis can lead to infertility in men.
West states that the "hardest thing about secondary fertility issues is that you want a sibling for your child." Fiona, who has a son of five and has been trying to conceive a second child for two years, says she can no longer look out of the window at her son playing in the garden. "It breaks my heart. He just looks so alone out there. All I want is a sibling for him but I don't think it's going to happen."
Some research has found that IVF may raise the risk of some very rare birth defects, but the risk is still relatively low. Research has also found that the use of ICSI with IVF, in certain cases of male infertility, may increase the risk of infertility and some sexual birth defects for male children. This risk, however, is very low (less than 1%).
Those fearful of conceiving with multiples should strongly consider IVF and only transferring one embryo at a time. In these circumstances, just 1% of pregnancies lead to twins, and triplets are even more rare. Alternatively, 8 - 30% of medicated IUI pregnancies lead to twins. Finally, the least preferable circumstance is do to IVF with multiple embryo transfer, where in women under 38 years of age, 30% of pregnancies culminate in a multiple birth.
For healthy couples in their 20s or early 30s, the chance that a woman will get pregnant is about 25 to 30 percent in any single menstrual cycle. This percentage starts to decline in a woman’s early 30s. By age 40, a woman’s chance of getting pregnant drops to less than 10 percent per menstrual cycle. A man’s fertility also declines with age, but not as predictably.
The best study in the field enrolled 750 women to receive clomid or letrozole, followed them for 5 courses of therapy and revealed that the group receiving letrozole had higher live birth rates and fewer multiple gestations. The data is of exceptional quality, and there’s no reason to believe the conclusion doesn’t also apply to the choice of drugs if these patients proceeded on to IUI.
Because not each IVF cycle that is started will lead to oocyte retrieval or embryo transfer, reports of live birth rates need to specify the denominator, namely IVF cycles started, IVF retrievals, or embryo transfers. The SART summarised 2008–9 success rates for US clinics for fresh embryo cycles that did not involve donor eggs and gave live birth rates by the age of the prospective mother, with a peak at 41.3% per cycle started and 47.3% per embryo transfer for patients under 35 years of age.
When it comes to fertility care, you deserve only the best. At CNY Fertility, we empathize with you and understand how stressful it is to be dealing with infertility. That’s why we never treat our patients as numbers or nameless visitors. From the moment you enter our doors, you’ll be welcomed by our friendly staff and receive only high-quality, personalized care. We believe that fertility treatments aren’t a luxury reserved for a select few – It’s a human right that you wholeheartedly deserve, no matter your history or situation. 
We also care about not only your physical well being, but also your emotional health. In fact, these issues as important enough to us that one of our core team members is a psychologist. Julianne Zweifel is an expert in addressing the mental aspects of secondary (and primary) infertility and she can promote emotional well being in a way that few others have the training or experience to do. If you should feel you do not wish to talk a specialist, but are struggling emotionally, please at least let other team members know-the more we hear from you, the easier it is for us to help.  

Anger, sadness, and anxiety are common among parents struggling to expand their family. "Having a child already doesn't make going through infertility any easier," says Alice D. Domar, Ph.D., executive director of the Domar Center for Mind/Body Health, in Waltham, Massachusetts, and author of Conquering Infertility. Meeting with a mental-health professional or seeking out blogs and online groups for secondary infertility can help. The website of  the National Infertility Association, resolve.org, is a good place to start.
Patients with hypothalamic dysfunction are not producing signals within their brains to tell the ovary to mature an egg. They are diagnosed because they have an extremely low FSH and a low LH (almost zero). Neither clomid nor letrozole will help them. For these patients, IUI must be accompanied by gonadotropin to be effective. From here on in this section, none of the data we’ll reference refers to patients with hypothalamic dysfunction.
Problems in the quantity or quality of eggs: Women are born with a limited supply of eggs and are unable to create new eggs after birth. As women approach their 40s and beyond, the numbers of eggs left in their ovaries decrease, and the remaining eggs have a higher chance of having chromosomal problems. For women where age isn’t a concern, there are other reasons that they might have a low number of good quality eggs, including autoimmune or genetic conditions and prior surgery or radiation.

In 2006, Canadian clinics reported a live birth rate of 27%.[11] Birth rates in younger patients were slightly higher, with a success rate of 35.3% for those 21 and younger, the youngest group evaluated. Success rates for older patients were also lower and decrease with age, with 37-year-olds at 27.4% and no live births for those older than 48, the oldest group evaluated.[12] Some clinics exceeded these rates, but it is impossible to determine if that is due to superior technique or patient selection, since it is possible to artificially increase success rates by refusing to accept the most difficult patients or by steering them into oocyte donation cycles (which are compiled separately). Further, pregnancy rates can be increased by the placement of several embryos at the risk of increasing the chance for multiples.
Addressing lifestyle issues is not meant to be a quick fix, and typically does not lead to instant success. However, with unexplained infertility every little bit counts, so don’t fret or give up. Do not assume just because the cause of infertility is unexplained, it is untreatable or there is no pathway to parenthood. When a specific cause is not determined for women, and male infertility has also been ruled out, our fertility specialist may begin a course of treatment to improve the chances of conception and pregnancy. The speed with which interventions are offered depends on each individual’s own needs and desires as determined by age and other factors.
Problems with your periods or menstrual cycle is a sign of ovulation problems – and if you aren’t ovulating, you won’t get pregnant. Menstrual problems are the most obvious sign of infertility in women – but they don’t necessarily mean you’re infertile. Most women have some type of problem with their period: light flow, heavy flow, clotting, irregularity caused by stress or weight fluctuations, hormonal changes, etc. 

The laboratory – This is when the harvested eggs are fertilized by an embryologist. Once fertilized, they’re grown 3-5 days until they’re able to be transferred into the woman’s uterus. Prior to the transfer, the embryos can be genetically tested. Although testing isn’t right for everyone, it’s useful for some people as it may help prevent miscarriage, passing on known genetic disorders, and can also be used to choose the sex of the child.
Sometimes problems getting pregnant for a second or subsequent time are related to a complication that occurred in a prior pregnancy or prior to delivery (damage to the uterus, for instance). But most often, secondary infertility is caused by the same factors that would cause primary infertility — issues like advanced age, obesity, ovulation problems and so on.
